JOSEPH G. BARLOW, OF QUINCY, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 329,994. dated November10. 1885- Application filed September 517, 1883. Serial No. 107,566.

T 0 all whom it may concern:

Be it known that I, JosEPH O. BARLoW, a citizen of the United States,and a resident of Quincy, in the county of Adams and State of Illinois,have invented certain new and useful Improvements in Corn-Planters, andI do hereby declare thefollowing to be a full, clear, and exactdescription of the invention which will enable others skilled in the artto which said invention appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures and lettersof reference marked thereon.

This invention relates particularly to improvements in that class ofcorn-planters for which Letters Patent of the United States No. 162,599were granted to me on the 27th day of April, 1875; and it consists incertain novel devices for adjusting and controlling the runner-framesand for securely locking the same in adjusted positions,which will behereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 represents a side viewof a corn planter containing and embodying my improvements, the nearwheel of the machine being removed and the runner-frame being shownlowered with the runners resting upon the ground. Fig. 2 representsasimilar view of the machine with the runner-frame shown raised up andlocked. Fig. 3 is a rear elevation of the machine adjusted as shown inFig.

Fig. 6 is a View of the crankshaft and of the pitmanconnected thereto. Figs. 7 and 8 are views, respectively, of the rightand left plates in which the crank-shaft has its bearings. Fig. 9 is adetached View of the left foot-lever. Fig. 10 is a view of thehand-lever, looking from the left. Fig. 11 is a view of the same,looking from the right, and showing particularly the recess or chambercontaining the spring-bolt or plunger, the cover for said recess orchamber being removed. Fig. 12 is a View showing in fulllines theposition of the hand-lever when pulled back to its fullest extent, so asto remain out of operation, and showing in dotted lines the (No model.)

position of the lever when engaged with are cess on the left foot-lever,so as to enable the driver to use it in tilting up the runner-frame.

Similar letters of reference in the several figures indicate the sameparts.

The letter A designates the runner-frame of the machine, carrying atopposite sides the runners B B. Upon this frame and over the runners arearranged the seed-boxes E E, and between the seed-boxes is the seat F,on which the dropper sits while he operates the seeddropping mechanismby means of the lever or handle E, arranged within convenient reach.

0 represents the rear or wheeled frame, mounted on the wheels D D, andhinged or jointed to the front runner-frame at a a, so as to permit thelatter to be raised or lowered by the tilting of frame 0, when desired.

The tongue G of the machine is secured to the runner-frame, and hasfastened to it a rearwardly-projecting extension, G, which projects backunder the wheeled frame 0 and be neath the seat-standard I, mounted onthe latter. The seatstandard is inclined backward and upward, andcarries atits upper end seat I for the driver.

K and K are suitable plates or castings bolted or otherwise secured tothe axle'piece G of the frame 0, and also preferably, though notnecessarily, bolted or otherwise secured to the right and left sides ofthe seat-standard, as shown in Fig. 3.

L is a crank-shaft having crankarms Z and Z projecting to the right andleft, respectively, and also having extensions Z and Zflwhich projectparallel to the outer portions of the right and left crank-arms,respectively, as shown in Figs. 3 and 6. The crank-arms ll of thecrankshaft have their bearings in suitable orifices in the plates K andK, respectively.- To the extremity of the crank-arm l, which projectsthrough the plate Kand to the extension Z of the crank-shaft, isconnected a foot-lever, M, having at one end a foot-rest, m, and at theother end a foot-rest, 0. I preferably connect this lever M in themanner shown-that is to say, by forming two orifices in it to fit overthe ends of the crank-arml and crank-shaft extension I, and clamp itsecurely in place by means of a screw-bolt, n, passed through the leverand into the crank arm, as shown in Fig. 3. This makes a very strong andsimple I CC) connection. The end of the crank-arm Z projects through theplate K on the opposite side of the seat-standard, and secured to it isthe left foot-lever, 1 said lever being provided with two orifices, one.for the crank-arm end and the other for the crank-shaft extension,

and being held in place by screw-nutsp p, as

ton ue-extension G as shown in Fi s. 1 2

z: 2 g a and 3.

The machine, as so far described, does not differ in essentialparticulars from that shown and described in my former patent referredto, and can be operated in substantially the same manner. Forinstance,the driver, sitting in his seat I, may, by manipulating the right andleft foot-levers with his feet, rotate the crank-shaft backward orforward, and thus tilt the frame 0 on its axis backward or forward, soas to raise or lower the front runnerframe and cause the runners to beraised from or to be pressed into the ground, as desiredthat is to say,by pressing with his left foot upon the foot-rest qof the leftfoot-lever, P, toinitiate the movement, and then with his right footupon the foot-rest m of the .right lever, M, to complete the movement,he can tilt the frame 0 backward and lift the runner-frame so as toraise the runners out of the ground. On the other hand, by pressing downwith his right foot upon the foot-rest o of the right lever, M, he cantilt the frame Oforward, and thus press .down the runner-frame and causethe runners to enter the ground more or less, and then by continuedpressure upon the foot-rest 0 keep the runners to their work.

Now, the object of my present improvements is, first,to provide meansfor locking the crankshaft when swung way forward or Way backward, orwhen stopped at any intermediate point, and thus enable the runners tobe held just where adjusted, whether in or out of the ground, or at anydesired depth in the ground; secondly, to provide a hand-lever soarranged as not to interfere at all with the free tilting of the framesup or down by the foot-levers, but capable of being engaged at the willof the driver in such manner as to assist the footlevers in theiroperation or take their places entirely and render their useunnecessary; and, thirdly, to so arrange the locking device upon thesaid hand-lever as to cause it to automatically operate to lock theframes when the runners are raised or lowered to the desired point.

The means which I have contrived for attaining the results mentioned areof very simple character, and will now be briefly described.

the crankshaft. On the outer side of the lever is cast or otherwiseformed a projecting lug or tooth, s,which,when the lever is raised andthen dropped, is adapted to engage with one or the other of a series ofrecesses or notches, b, formed in a segmental portion of the lever P,-asshown in Fig. 2, as will be further on explained. On the inner side thesaid lever is formed with a socket or chamber, 1", in which is arrangeda sliding bolt or plunger, v; This bolt or plunger is preferablyarranged so as to be capable of being projected or retracted through theend of the socket. Within the socket it is provided with lateralprojections r 1, and an upper extension, r which serve to guide it inits movements,and it is further provided with a longitudinal slotm,through which passes the pin .2, that secures the covering plateor capa; of the socket or chamber in position. or plunger itself may be reliedupon to effect its projection at the proper time; but I preferablyinsert within the socket above it a spiral spring, to, "in order toinsure its positive action at all times. The upper portionof the plate Kis provided with a ledge, k, and also with a somewhat higher ledge, andin the ledge k a recess, k is formed for the reception of the bolt orplunger '0, carried by the lever. At the forward side of the plate K aprojecting stop, It, is arranged for the purpose of limiting the forwardswing of the lever, while at the rear side of said plate another stop,7c*, is provided to limit the swing of the lever in that direction. Whenthe lever is raised (its elongated slot permitting this) and swung backto its fullest extent, its spring bolt or plunger will rest upon theledge k", and the hook-shaped lug r formed on its rear edge, will hookover the rear stop, k as shown in Fig. 8. While the lever is in thisposition, the foot-levers can be freely worked so as to tilt the frame 0and raise and lower the runner-frame, as in the old machine. If, now,the driver desires to lock the crank-shaft at any particular pointbetween its extremes of movement, he simply manipulates the footleversuntil the particular point desired is reached, and then slightly raisesthe handlever and moves itcforward until its spur or lug s engages withone of the notches in the lever P, on the one hand,while its spring boltor plunger engages with the recess or notch k lever and throw it forwardand engage the left lug .or tooth, s,with one of the notches b of thefoot-lever P that is forward of the notch k in the ledge of plate K, andthen by pull- The weight of the bolt 1 ing backward upon the lever hecan still further rotate forward the crank-shaft and cause the runnersto be pressed into the ground to the fullest extent, and when this pointis reached the lever will have traveled back to the shoulderof the ledge76*, which reached,

the spring bolt or plunger will automatically drop into the notch k andthus hold all the parts securely locked in position and prevented fromfurther movement. To unlock the hand-lever from this last-describedposition, a pressure downward and forward on the foot-rest 0 of theright-hand foot-lever, M, will generally be necessary in order to unbindand relieve the handlever and enable it to be raised sufficiently todisengage its lug and its bolt or plunger from their respective recessesor notches. In fact, it may be given asa general direction that torelease the lever after it has once locked the parts at any given pointthe releasing operation will be much facilitated by operating thefoot-levers so as to free the said hand-lever from lateral pressure. Thehand-lever may also be utilized, if desired, in raising the runners fromthe ground by causing its side lug or tooth to engage with theappropriate recess of the foot-lever P, as will be readily understood.

It will be observed that the hand-lever,when engaged with thefoot-lever, is to all intents and purposes a part of said foot-lever,and controls the crank-shaft and connections just as completely as doesthe said foot-lever, and, in fact, more completely.

The most important feature of the handlever is its complete adjustability,whereby the driver is enabled to apply it to the foot-leverjust when and where the necessities of the case demand. Until theoccasion for its use arises it remains swung back out of the way, notinterfering in the slightest with the maintenance of the full control ofthe machine by means of the foot-levers. The locking of the runners atany point, or the raising or lowering of them, equally fall within itssphere of usefulness. It is not so permanently connected to thefoot-levers as to be vibrated back and forth in front of the driver, asthe runners are made to rise and fall to suit the requirements of thework performed, but remains out of the way till the occasion for its usearises. Moreover, being independent of the foot-lever and crank-shaft, arange of movement is given the latter not possible if it were rigidlyand permanently connected to them.

Having thus described my invention, I claim as new 1. The combination,in an agricultural implement, of the crank-shaft, the foot-leverconnected thereto having the circular series of notches or recesses, andthe loose longitudinally-movable hand-lever having the lug for engagingwith the notches of the foot-lever, substantially as described.

2. The combination, in an agricultural implement, of the crank-shaft,the plates in which it is j ournaled, the foot-lever having the seriesof notches or recesses, the adjustable lever having the lug for engagingthe notches of the foot-lever, and the bolt or plunger for engaging thenotches of the stationary plate, substantially as described.

3. The combination, in an agricultural implement, of the crank -shaft,the foot-lever connected thereto and having the series of notches, andthe longitudinally-movable handlever having its fulcrum on the arm ofthe crankshaft, and provided with the lug for engaging with the notchesof the foot-lever, substantially as described.

4. The combination, in an agricultural implement, of the crankshaft, theplates in which it is journaled, one of which has the ledges and notch,of the foot-lever having the series of notches, and thelongitudinallymovable adjustable hand-lever having the side lug ortooth, and the automatic bolt or plunger, substantially as described.

5. The combination, in an agricultural implement, of the crank-shaft,the plates in which it is journaled, one of which has the ledges andnotch, the levers on opposite ends of the crankshaft, one of which hasthe series of notches or recesses, and the adjustablelongitudinally-movable hand-lever provided with the side lug andautomatic bolt or plunger, substantially as described.

6. The combination, in an agricultural implement, of the crank-shaft,the plate K, and the adj ustable lever adapted to be swung back andlocked to the plate K by its rear hook engaging with the rear stop,substantially as described.

7. The combination, with the notched footlever of the corn-planter, ofthe adjustable hand-lever adapted to be thrown into or out of engagementwith the said foot-lever at will. and carrying the automatic bolt orplunger for automatically looking it when swung back from a forwardposition, substantially as de scribed.

8. The hand-lever having the oblong slot in its lower end, and theautomatically-operating bolt, substantially as described.

9. The hand-lever having the oblong slot in its lower end, the lug, andthe automaticallyoperating bolt or plunger, substantially as described.

10. In a planter, the hand-lever having the recess or chamber, the boltor plunger within the chamber having the slot in it, the spring forprojecting the bolt, the cap-plate, and the screw for holding the samein place, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand,this 4th day of September, 1883, at Quincy, Illinois.
